Hi all,
My problem is that I would like to reshape a specific matrix in the form that I desire for my calculations, however I don't seem to be able to get it exactly as I want. Here is the specific example to my problem:
I have the following code:
a = [1 2 3 4] ;
b = [5 6 7 8] ;
[x, y] = meshgrid(a,b) ;
A = x ;
A(:,:,2) = y ;
The above gives me an output as I desire, in the following form:
A(:,:,1) =
1 2 3 4
1 2 3 4
1 2 3 4
1 2 3 4
A(:,:,2) =
5 5 5 5
6 6 6 6
7 7 7 7
8 8 8 8
At this point, I would like to create another matrix called B, based on A, such that:
B = [1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4
5 5 5 5 6 6 6 6 7 7 7 7 8 8 8 8] ;
I have tried using reshape to accomplish the above however I cant get this output from it.
Your help would be appreciated,
KR,
KMT.

a = [1 2 3 4] ;
b = [5 6 7 8] ;
B = [repmat(a,1,4);repelem(b,4)];
or
reshape(permute(A,[2,1,3]),[],2)';
